Patent DE-3806666-A1 (DE)
Title: Switch-off engine indicator for motor vehicles
Inventor: KLENK MANFRED
IPC: B60Q1/50
Filed: 1988-03-02
Abstract: "Please switch off engine" indicator systems on relatively large traffic control systems are known but are seldom found. In relatively large queues of traffic in front of traffic lights, an existing indicator signal is often missed by the car drivers at the rear. "Please switch off engine" signs are not found at traffic lights at roadworks, in congestion or in the case of relatively long waiting times at railway crossings. The new "switch-off engine" indicator is generally attached on the inside to the rear window or to the rear. When the engine is switched off, the sign "please switch off engine" lights up in words or symbols with the indication "for the sake of the environment". As a result, the car driver behind is likewise told to switch off his engine. By means of this device, the car driver is motivated to protect the environment. In turn, a large contribution to protecting the environment is thus made.

Title: Method for transmitting 2 or more channels with an alternating current and/or frequency reduction of an alternating coding current
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/36
Filed: 1988-05-19
Abstract: It is known for a plurality of channels to be transmitted via only one transmission path in frequency or time division multiplexing. However, these methods are very expensive. In the present invention, transmission of this type is performed using code division multiplexing, i.e. the values extracted synchronously or derived quasi-simultaneously are coded, transmitted and re-allocated to the different channels at the receiving end through the decoding.

Patent DE-3822538-A1 (DE)
Inventor: RABENSTEIN HEINRICH
IPC: H01M10/10
Filed: 1988-07-04
Abstract: A lead storage battery with gel-like thickened acid electrolyte has a separator (1) ribbed on both sides, the ribs (3) of which are many times wider than the channel-like depressions (4) between them, which thereby take on the function of vertical gas channels and in particular facilitate an escape of the oxygen developed during charging from the adjacent electrode plates. It is just as easy for this oxygen to reach, from above and via the gas channels at the rear, the negative electrode, at the surface of which it is evenly consumed. Ribs and basic separator sheet (2) are preferably made of different materials, the former of macroporous PVC. <IMAGE>

Title: Electrical current compression for increasing the efficiency of direct energy converters
Inventor: BECKERS ROBERT
IPC: H02S99/00
Filed: 1988-07-07
Abstract: In order to increase the efficiency of conversion of heat energy or radiation energy into electrical energy with the help of direct converters such as thermocouples, thermionic converters, solar cells and the like, a direct converter can be operated using a current compressor driven by the converter itself. In this case, according to the drawing hereinbelow, a direct electrical current generated by a direct converter Ew flows via the DC voltage converter Gsw into the capacitor C. In order to achieve a higher current density and a corresponding higher efficiency in the direct converter, the electrical voltage of the capacitor C is connected in series with the electrical voltage of the direct converter Ew. The resistance of the connected load RL is designed so that the current coming from the capacitor C drops at it and flows back into the capacitor C again via the DC voltage converter Gsw. The conversion losses originating in the DC voltage converter must be made up for from the useful electrical energy generated in the direct converter. <IMAGE>

Patent DE-3833430-A1 (DE)
Inventor: HOFBAUER PETER PROF DR ING
IPC: F02M37/12
Filed: 1988-10-01
Abstract: Excess fuel delivered under pressure by a mechanical fuel pump 1 mounted on an internal combustion engine is used as an extra source of power for driving an auxiliary, hydraulically powered pre-feeder pump 11. A pressure reservoir 24 equipped with a pressure-balancing chamber 25 is interposed between the pro-feeder pump 11 and the main fuel pump 1. The flow of fuel reaching the pressure reservoir 24 from the hydraulic pump 11 is controlled by a valve 26 which is opened when the pressure-balancing chamber 25 of the pressure reservoir becomes empty, and remains open as long as the fuel continues flowing to it. The excess fuel reaches the pressure reservoir from the main fuel pump through a pressure channel 7, from where it flows into a chamber 27 of the pressure reservoir situated between the valve 26 and the hydraulic pump 11, or between the valve 26 and the channel 23 leading to the pre-feeder pump. <IMAGE>

Title: Power-supply installation for motor ships with fixed pitch propeller
Inventor: KRANERT KLAUS DR
IPC: F02B3/06
Filed: 1988-10-26
Abstract: A continuous and uninterrupted power supply on motor ships even in the event of a reduction in the output and/or number of diesel engines is to be ensured. The shaft-driven alternator (7) feeds into the ship's electrical system (1) in the entire operating-speed range (i.e. from +/- 100% to +/- 25% of the rated speed) of the main engine (4) during ahead and astern speed. Both diesel units (13, 14) are each designed for approximately half the power (0.5.PN) of the ship's electrical system and can be switched to a common sectional bus-bar (15). The shaft-driven alternator (7) is designed in such a way that, together with a diesel unit (13, 14), it covers the reduced power of the ship's electrical system at the minimum speed (25% of the rated speed) of the main engine (4). The installation enables investment and maintenance costs to be saved on account of the use of more electrical components and less machine parts prone to wear. <IMAGE>

In order to make the installation of a knee restraint element (3) of this type in a motor vehicle which, for example, also has a centre console, as simple as possible, the intention is for the restraint element to comprise two sub-elements (3a, 3b) with associated hollow-profile support parts (4a, 4b), the cross-sections of which are dimensioned in such a manner that the support parts can be inserted one into the other over a finite length to produce a positive connection. Expediently, the hollow-profile support parts (4a, 4b), which can be inserted one into the other, are still to be connected releasably to one another. <IMAGE>

Patent DE-3919990-A1 (DE)
Title: Control of the steering angle of vehicles
Inventor: HATTORI KATSUHIKO
IPC: B62D137/00
Filed: 1989-06-19
Abstract: A steering aid (power steering system) of a motor vehicle has a steering angle sensor which is coupled to the steering wheel and whose output signal is converted into an adjustment signal for the steered wheels of the vehicle by an electronic control unit. The steering angle of the wheels is detected. The adjustment of the wheels takes place by means of a power control device via a (hydraulic) aid. The latter acts on a steering angle detector so that the wheel adjustment brought about by the aid device is detected mechanically. In the event of a deviation between the detected steering angle of the wheels on the one hand and the steering angle determined by the turning of the steering wheel on the other, a displacement signal is produced. The auxiliary force for adjusting the steered wheels is controlled as a function of the signal which is derived from the steering angle of the steering wheel, the displacement signal and the detected steering angle signal of the wheels. In this way, even in the event of a failure of the steering aid system the vehicle can be easily controlled with relatively little force. In addition, course deviations as a result of external forces (gusts of wind) are corrected. <IMAGE>

Title: Radio data signal receiver for motor vehicle - initiates interruption mode by data contained in demodulated radio waves for traffic news
Inventor: KASA KOICHI
IPC: H03J1/00
Filed: 1989-10-13
Abstract: The receiver has a demodulator for demodulating the radio data signal radio waves fed to a data processing circuit which switches to an interruption mode when an interruption data is supplied from the demodulator. A decision stage determines whether or not the received radio data signal radio waves can be demodulated, e.g. by evaluation of the reception strength, with the processing circuit prepared for swtiching to the interruption mode when the radio waves cannot be demodulated. Pref. the decision stage detects the block synchronisation of the data from the demodulator. USE - Providing traffic information.
